Precious Machined Graphite copper sleeve JDB 4*8*10 Metallurgical equipment bushing
Dimensional accuracy matters more than raw hardness in a pivot bush, and the JDB4*8*10 sleeve is finished on CNC centres to hold bore roundness and length tolerance tightly. Graphite columns are set at an angle that follows the main load direction of Metallurgical equipment joints.
